FRANK AUGUSTES ELSTER, 0F VALLEJO, CALIFORNIA.

; GAS GENERA OR AND: BURNER.

To all whom it may concern:

Be it known that; I, FRANK A. ELSTER, a

citizen of the United States, residing at Vallejo, in the county of Solano and State of useful Improvements in Gas Generators and bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for itsobject to provide a simply constructed and inexpensive, yet a highly eflicientand in every Way desirable 7 tion.

' lower end of device for generating gas from rather poor grades of oil and then consuming-the gas, the construction being such as to permit quick and easy disassembling of theburner for cleaning.

With the foregoing object in view, the invention resides in the novel features of construction and unique a'rran'gementof parts hereinafter fully described and claimed, reference being made to the accompanying drawlngs forming a part of this specifica- Figure 1 is a side elevation of the burner.

Fig. 2 is a vertical section thereof.

Fig. 3 is an additional vertical section at right angles to Fig. 2. a

Fig. 1 is a horizontal section as seen-on the plane of the line 4 l of Fig. 3.

In the drawings above briefly described, the numeral 1 designates a preferably cast metal pan having a central stud 2 rising a suitable distance for tapping into the bothaving a plurality of openings 5 so that the lower end of the dome is in effectopen. A frusto-cone-shaped jacket "*6 surrounds the dome 4: and extends above the 'same, the said jacket I being threaded around the lower end of'the dome as seen at 7, while the upper-end of said jacket is provided with an inwardly extending flange 8 into which the upper end of a tubular heat passage member 9 is threaded, said passage I member extending within the upper portion of the acket 6 and being tapped at 10 into the topof the dome 4. Both ends of the passage member9 are open and the lower end thereof communicates with the nterror of the dome as shown. By means of a tune Specification ofLetters Patent.

- 11 having a valve 12, oil is fed into the chamber '13 formed between said chamber 13, between the jacket and the dome, is relatively narrow as shown at 14 Burners; and I do declare the followlng to so as to receive and heat a thin sheet of oil as indicated clearly in Figs. 2 and 3. The

heating the oil.

A cylindrical super-heating casing15 is 'positioned in the passage member 9 in spaced relation to the wall thereof, the lower end of said casing being closed at 16 while threaded into the upper end of said casing, said nipple having a suitable burner 18 and being provided with a passage 19 leading from the casing 15 into said burner. It will be observed that the outlets from the burner 18 are so directed as to cause the flame to'strike the Walls of a fire box or other suitable container in which the burner is used, thus directing such flame 1 around the entire device to maintain it at a sufiiciently high temperature to gasify the oil fed thereto. The generated oil vapor risesinto the upper end of the chamber 13 and passes through tubular passage members 20 into the super-heating casing 15, and after the super-heating takes place in this casing, the gas is discharged through the passage 19 to the burner. tom 3 of a cast metal dome 4,"said bottom- Preferably employed in connection with the features of construction so far described, is a vertical tube 21 located between the easj ing 15 and the passage member 9, the upper burner 23-is employed to generate suiiicient heatto cause vaporlzatlon of the 011.

In operation, the device is either placed in a fire box or othersuitable casing, or is employed in the open, according to th e conditions encountered. The pan 1 1s mitially and such fuel is ig V I dome' 4t, and the jacket 6, and 1t will be observed that the lower portion of California, have invented certain new'and nited to heat the entire device before the gas is ignited. As soon as suflicient gas has generated, it islighted as it is discharged from the burner 18 and if the device is employed in a fire box or the like, the heat from this burner, being thrown downwardly around the jacket 6, will maintain the latter and all parts at a suflicient high temperature to vaporize the oil, but if the device is not use in a container, the valve 22 is opened'and the small burner 23 is used for heating the device to the proper temperature.

The hot metal in contact with the thin sheet of oil in the space 14, quickly vaporizes such oil so that the vapor rises within the upper portion of the chamber 15 and is still further heated. From this chamber, the vapor passes through the passage members 20 into'the superheating chamber 16 and after the super heating operation it becomes highly volatile gas which is discharged through the passage 19 into the burner 18 and consumed by the latter;

The device may be easily disassembled for cleaning and I preferably provide the jacket with lugs 25 to engage a wrench when this is done.

From the foregoing, taken in connection with the accompanying drawings, itiwill be obvious that although the device is of extremely simple and inexpensive nature, it will be highly efficient and desirable, and since probably the best results are obtained from the details shown and described, they are by preference followed. It is to be understood however that within the scope of the invention as claimed, numerous minor changes may well be made.

I claim:

1. In a gas generator and burner, a dome having an open bottom to admit heat, a contracted passage member rising from and communicating with the upper end of said dome, the upper end of said passage member being open to allow the escape of the heat, a jacket surrounding said passage member and dome and forming therewith a gas generating and heating chamber, the ends of said jacket being secured in a fluid tight manner to said dome and passage member respectively, a liquid fuel inlet into said chamber, a gas outlet therefrom leading through the wall of said passage member, a burner, and gas conducting means leading from said outlet through said passage member to said burner.

2. In a gas generator and burner, a dome open at its bottom, a heat passage member rising rigidly from and supported by said dome, both ends of said passage member be ing open and the lower end of said passage member communicating with said dome, a jacket surrounding said dome and passage member in spaced relation thereto and secured to both at its ends to form therewith a fluid tight generating chamber, an oil inlet into said chamber, the lower portion of said jacket and said dome being in closely spaced relation to provide for the reception and quick heating of a thin sheet of oil, while'the upper portion of said jacket and said passage member are spaced apart a greater dis tance to receive the generated gas, a burner, and means in said passage member for supplying the gas to said burner from said chamber. 7

3. Ina gas generator and burner, a dome open at its bottom, a heat'passage member rising rigidly from and supported by said dome, both ends of said passage member being open and the lower end ofsaid passage member communicating with said dome, a jacket surrounding said dome and passage member in spaced relation thereto and secured to both at its ends to form therewith a fluid tight generating chamber, an oil inlet into said chamber, a gas superheating casing in said passage member in communication with said chamber and spaced from the wall of said passage member, a burner, and a passage from said superheating casing to said burner. r

5. In a gas generatingand consuming de vice, a dome provided with an open bottom and having a central opening in its top, a tubular passage member received at its lower end in said opening and rising rigidly from said dome, a jacket surrounding said dome and passage member in widely spaced relation with the latter and in closely spaced relation with the former, the lower end of said jacket having a fluid tight connection with said dome, and the upper end of said jacket having an inwardly extending flange surrounding the upper end of said passage member, a superheating casing losated, in. said passage member in spaced relation with the Wall thereof, other passage members supporting said super heating casing and establishing communication between the same and the space between said jacket and said first named passage member, a nipple rising from said supei'heating casing, and a burner carried by said nipple, the latter having a passage for supplying gas to said burner from said superheating chamer. In testimony whereof I have hereunto set my hand.
